Neptune square Lilith (orb 1.6°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Neptune in Leo in House 9 brings imagination, image, popularity, collective moods, and inspiration into House 9 (vision, belief, study, and wider horizons), with Leo style (presence, pride, creation, and the wish to be seen); Lilith in Taurus in House 6 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 6 (daily work, technique, and bodily discipline), with Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance).
Concrete friction: this aspect puts Neptune (imagination, image, popularity, collective moods, and inspiration) and Lilith (pure ideal, absolute demand, fascination, and refusal of compromise) into repeated friction: one can interrupt, inhibit, or provoke the other in concrete situations. Visible angle: Lilith near the Descendant (orb 4.5°) touches an angle; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met. House 9 (vision, belief, study, and wider horizons) is in friction with House 6 (daily work, technique, and bodily discipline); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
